Rosemond, 47, was indicted for conspiring with five other men to kill the associate, Lowell Fletcher, in 2009.

"This has not been a good month for Jimmy the Henchman," Raymond W. Kelly, the New York police commissioner, said in a statement.

Rosemond's lawyer, Gerald L. Shargel, did not immediately respond to requests for comment.

Rosemond is notorious in the hip-hop community for his alleged involvement — which he has consistently denied — in the bicoastal feud that led to the murders of rappers Tupac Shakur and Christopher Wallace, known as Biggie Smalls.

He served as the CEO of Czar Entertainment which managed big-name artists including the Game, 50 Cent, Akon, Brandy and boxer Mike Tyson.
